Title: Immunoassay of antigens or antibodies - using chemical reagent as label
IPC: G01N33/542
Filed: 1975-08-21
Abstract: In the determn. of antigens (or antibodies) in biological fluids by immunochemical reaction with antibodies (or antigens), the antigen is labelled with a reagent which (or a fragment of which) is readily analysable. After reaction of the labelled antigen with the test substance, the released reagent (or fragment) is directly determined. The use of radioactive isotopes is avoided. The reagent is pref. a coumarin deriv., esp. 4-methylumbelliferone (MU) or its succinate ester, which is coupled with the antigen via an amino gp. in the latter (any other reactive gps. being blocked). For antigens not contg. amino gps., coupling can be effected via an esterified amino acid. The labelled antigen can be purified by thin-layer or column chromatography. The reagent is determined fluorometrically.

Title: Vineyard post formed as closed steel section - has equidistant slots with larger beading on long edges than cross-ways, to receive inserted wire hooks
Inventor: REISACHER JOSEF DR ING
IPC: A01G17/14
Filed: 1977-01-26
Abstract: Vineyard post as a closed steel section has slots with beaded rims at equal spacing, the beadings being larger lengthways than in the transverse direction.
